Myerson's statements supposedly didn't clarify whether the same apps would technically work on the operating systems or if developers would make an app for the respective platforms that would share a store listing.

At Microsoft's financial analyst meeting last week, Myerson said the company was working on a common app platform that would be shared across its operating systems, possibly even including the company's Xbox One operating system.

"The first of [our beliefs about how our operating systems should work] is that we really should have one silicon interface for all of our devices," he said. "We should have one set of developer APIs on all of our devices. And all of the apps we bring to end users should be available on all of our devices."

Microsoft has been criticized for its lack of a common store between its desktop and mobile operating systems, forcing consumers to buy apps such as "Halo: Spartan Assault" twice if they wanted to use them on Windows and Windows Phone devices. Google's Android and Apple's iOS, by comparison, allow users to purchase apps that are playable on both smartphones and tablets.
